Shape the roast into small meatballs and fry in a pan with a little oil. Add the gnocci and fry them briefly; put aside.
Peel and halve the cucumbers and remove the seeds with a spoon. Cut the cucumber into bite-sized 1 cm pieces. Chop the onion and fry in another pan. Add a little water and salt as well as the cucumbers and let simmer with the lid closed for 5 minutes. Add the cream and crème fraîche, thyme and rosemary and stew for another 5 minutes.
Then add the dumplings and gnocci, mix well and season with salt and pepper, paprika and 1 teaspoon of mustard and let steep for another 5 minutes.
